Self-attenuating properties

The articles from polysulfone possess self-attenuating properties, caused by the nature of polymer but not of the additives. The values of oxygen index for polysulfone lie in the range of 34-38%. Apparently, aromatic polysulfones damp down owing to the formation of carbonized layer, becoming porous protective cover, on their surfaces. The probable is the explanation according to which the inert gas is released from the polymer [8].

There seems to be tremendous buffer and networked self-control against overshooting and attenuated immune response. Only extreme alterations appear to result in clinical symptoms as the majority of immune cells are never challenged by supposed threats, i.e., pathogens or correctly or not identified constituents of the body as malignant. We lack thresholds of adversity for immu-nomodulation, where they do not represent an increased incidence of disease when the immune response is inadequate. This would be a prerequisite for establishing any screening for immunotoxic instead of immunomodulatory properties.
